Case Study: Three Gorges Dam

(May 15, 2008) Though the deadly Wenchuan earthquake was the result of tectonic stresses, experts are concerned that the filling of the Three Gorges dam’s enormous reservoir may have induced or exacerbated the earthquake.

China’s deadly earthquake: Was the Three Gorges reservoir a trigger?

(May 14, 2008) The world’s earthquake experts have identified tectonic plate movements as the cause of this week’s earthquake in southwestern China. But the question now is did the filling of the massive Three Gorges reservoir, which reaches the southeastern part of the Sichuan Basin, trigger seismic activity in what has always been an earthquake-prone region? 

How Dams Fail

(May 1, 2008) There are different types of dams classified by the material and design used in construction. These differences influence how and why dams fail. A dam can be classified by its material, indicating whether it is earthen or concrete. Dam components can also include iron, steel or timber or a combination of any of the above.

Possible earthquake and bank stability due to the reservoir

The possible earthquake issue due to Three Gorges reservoir has been emphasized by the government for a long time, and extensive researches have been made on the issue involved in the rock, geologic structure, osmosis, etc. A 300~800 m deep-hole earth stress observation is carried out at dam and reservoir site and the earthquake intensive observation is made on some fracture zones around the dam. According to the researches, the geologic structure is stable, and has no geological background for a

Geographical overview of the Three Gorges dam and reservoir, China—geologic hazards and environmental impacts

(2008) The Three Gorges dam and reservoir are an ongoing project that will involve a continuous process of construction, maintenance, monitoring, evaluation, and modification. Some of the history, construction characteristics, hydropower statistics, environmental and population impacts, monitoring, and current and potential hazards of the massive dam project are presented in this Microsoft PowerPoint® format.
